但由于提前角减小，排气背压增大，发动机燃油消耗率上升8%左右。

But because of reduced injection timing and increased exhaust back pressure, the BSFC of the engine will be increased of 8%.

通过对模糊控制器的设计，计算出EQ6 10 0汽油机在不同工况下的排气门提前开启角和进气门滞后关闭角的模糊控制值。

The fuzzy control values of the optimized exhaust lag angle and intake advance angle of the EQ6100 engine are calculated by designing the fuzzy controller.

试验结果表明，催化转化器的位置距排气口近可提高排气温度，大大提高催化转化器的转化效率；推迟点火提前角和提高怠速转速均有利于使催化转化器进入快速起燃状态。

Experimental results show that the position of the converter nearer to the exhaust port, the retard ignition timing and the higher idle speed can promote the catalytic converter light-off.
